> Adobe After Effects CS5.5, does it only come in 64 bit?
Yes. See the system requirements.
This page has information on advantages of 64-bit software.
> Can you still download a trial of CS4?
CS5.5 Production Premium & Master Collection (Windows) include Premiere Pro CS4 & After Effects CS4. See this page.
